18. 2011 SharePoint Results Summary
Hyper-V R2 SharePoint Workload Scalability
• Up to 460,800 simulated SharePoint users*
• As expected, the front end is the bottleneck during single web server VM
testing
• Adding web server VMs alleviates the bottleneck
• Response times improve and more requests per second are delivered as
VMs are added
• 90% scaling efficiency from 1 to 2 web servers**
*1% concurrent users derived from the requests per second measured during the three web server test
** Based on a comparison of requests per second divided by average page response time

19. The Bigger Truth
Why This Matters
Performance scaled and response times dropped as Hyper-V R2 web server VMs were
added to a consolidated SharePoint deployment on a single physical server.
The manageably low performance impact of Hyper-V R2 won’t be detected by the vast
majority of end-users and applications.
The performance, scalability, and low overhead of Hyper-V R2 can be used to reduce
costs and improve the manageability, flexibility, and availability of consolidated
SharePoint applications.

20. Issues to Consider
• Mileage varies; test with your workloads and your data
• Hyper-V
• Included for free with Windows Server 2008
• Proven to perform with demanding applications
• Size matters
• Application and web server roles are good candidates for virtualization
• For larger deployments, consider deploying resource-bound SQL Server and Index
roles on physical servers
• High availability matters
• Leverage ESG Lab Validations, Microsoft and its partners’ best practices/proof points

21. Microsoft/Intel iSCSI test
• Used Windows Server 2008
R2, Intel Xeon 5500
processors, and Intel 10Gbps
Ethernet Adapters
• Reached over One Million IOPS
over a single 10 Gbps Ethernet
link using a software iSCSI initiator
on Native HW
• Reached over 700,000IOPS over a
single 10 Gbps Ethernet link using
a software iSCSI initiator on
Hyper-V to the Guest OS
